Answer/Explanation:
Rivers support trade into distinct ways. First, they provide trade routes to carry products to the seas for shipping.
Secondly, they create arable land because of the nutrient-rich soil deposited in river basins. The water from rivers can also be delivered to farmland to water crops, a process known as irrigation.
Because water is a scarce resource overall in this region, many residents rely on subsistence agriculture, which means maintaining small farms that produce only enough for the survival of a single family. This is different than commercial agriculture, which means producing crops on a mass scale for a profit, and requires a large amount of water for irrigation.
Deserts make trade more difficult because travel is difficult and they cannot support farming. Some people manage to make a small living in the desert by nomadic herding and trading. Interestingly, many (but not all) desert nations have found economic success due to the presence of a very valuable natural resource: oil. Oil is one of the most precious resources shipped along the waterways of the Middle East.
